说明:   在linux平台下,纯c写的盲信号分离的代码.它采用基于卷积混合的盲信号分离算法,不但可以分离人工合成的混合信号,而且对于真实环境中的卷积混合的语音信号也能够分离.在本程序中,包含了两个测试文件,makefile后便可以直接使用. 另外值得一提的是,压缩包里包含有一些语音处理方面的常用函数.例如fft变换,读取\写入wav文件,以及一些常用的一维向量和二维矩阵变换的函数.这些可以直接应用在其他应用程序里去.
(in linux platform, net write c Blind Signal Separation code. it is based on convolution of mixed Blind Signal Separation algorithm, not only can be separated from the artificial synthesis of mixed-signal, but for the real environment convolution of mixed voice signals can be separated. in this procedure, the tests included two documents, makefile can be used directly after. Also worth mentioning is that Compression bag containing some of voice processing functions commonly used. fft transform, for example, to read \ write wav file, and some of the commonly used one-dimensional and two-dimensional vector matrix transformation functions. these can be directly applied to other applications going.)

If you "make", you will have three executable files which are, "ica", "ica_f", and "ica_online". ica : blind source separation for linear mixtures. ica_f : blind source separation in time-frequency domain. ica_online : online version of ica_f. to know the usage and options, just type the one of the three names and CR. Two wav files are included for test. X_linear.wav : test file for ica. X_room.wav : test file for ica_f anc ica_online. If you have a wav file recorded in stereo, 16kHz sampling rate, you can try ica_f or ica_online (or ica) on it. Shiro Ikeda, shiro@ikeda.cc
